Abstract
The device for moistening the flaps of envelopes as they are driven along a substantially horizontal plane comprises a substantially vertical brush (1) caused to rotate with a peripheral speed substantially equal to the speed at which the envelopes are driven, and fed with moistening liquid taken from a tank (3) by means of a peristaltic pump (4), with the envelope flaps being pressed against the brush by means of a deflector (2).
